Passage 1 kQtnT7
In contrast to traditional analyses of minority business, the sociological analysis contends p-%m/d?
that minority business ownership is a group-level phenomenon, in that it is largely dependent upon u|&
a!tOf2
social-group resources for its development. Specifically, this analysis indicates that support ^Pc&`1Ap
networks play a critical role in starting and maintaining minority business enterprises by providing M7AUY#)
owners with a range of assistance, from the informal encouragement of family members and n{.SNipU
friends to dependable sources of labor and clientele from the owner’s ethnic group. Such self-help -<n]Sv;V
networks, which encourage and support ethnic minority entrepreneurs, consist of “primary” H?'t>JX
institutions, those closest to the individual in shaping his or her behavior and beliefs. They are G~\=:d=^,`
characterized by the face-to-face association and cooperation of persons united by ties of mutual 'Y-Y
By :
concern. They form an intermediate social level between the individual and larger “secondary” pGSS
institutions based on impersonal relationships. Primary institutions comprising the support -$kAWP8P4
network include kinship, peer, and neighborhood or community subgroups. *8xMe
A major function of self-help networks is financial support. Most scholars agree that minority Ha20g/UN.
business owners have depended primarily on family funds and ethnic community resources for l=t$XWh!
investment capital. Personal savings have been accumulated, often through frugal living habits i}e OWi
that require sacrifices by the entire family and are thus a product of long-term family financial !qVnziE,,
behavior. Additional loans and gifts from relatives, forthcoming because of group obligation Z"'tJ3Y.~
rather than narrow investment calculation, have supplemented personal savings. Individual co%-d
entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing i;}mIsNBY
from commercial resources. They may actually avoid banks because they assume that commercial y8=H+Y
institutions either cannot comprehend the special needs of minority enterprise or charge ~i/K7qZ
unreasonably high interest rates. ygf
Uy
Within the larger ethnic community, rotating credit associations have been used to raise "94qBGf
capital. These associations are informal clubs of friends and other trusted members of the ethnic dgM@|&9*m
group who make regular contributions to a fund that is given to each contributor in rotation. One )Fh5*UC
author estimates that 40 percent of New York Chinatown firms established during 1900-1950 E >lW'
utilized such associations as their initial source of capital. However, recent immigrants and third O;?Nz:/q
or fourth generations of older groups now employ rotating credit associations only occasionally to 0P_3%
raise investment funds. Some groups, like Black Americans, found other means of financial _G=k^f_
support for their entrepreneurial efforts. The first Black-operated banks were created in the late u~q6?*5
nineteenth century as depositories for dues collected from fraternal or lodge groups, which U/3<p8
themselves had sprung from Black churches. Black banks made limited investments in other Black {pyTiz#JY
enterprises. Irish immigrants in American cities organized many building and loan associations to rWB/#m
provide capital for home construction and purchase. They, in turn, provided work for many Irish eJwHeG
home-building contractor firms. Other ethnic and minority groups followed similar practices in vX/("
[
founding ethnic-directed financial institutions. ,c9K]>8m`

Passage2 4'TssRot@h
It was once assumed that all living things could be divided into two fundamental and gJ~CD1`O
exhaustive categories. Multicellular plants and animals, as well as many unicellular organisms, are ^7a@?|,q8
eukaryotic—their large, complex cells have a well-formed nucleus and many organelles. On the M:dH>
other hand, the true bacteria are prokaryotic cell, which are simple and lack a nucleus. The &8I}q]'k
distinction between eukaryotes and bacteria, initially defined in terms of subcellular structures +cM~
|
visible with a microscope, was ultimately carried to the molecular level. Here prokaryotic and vqZBDQ0
eukaryotic cells have many features in common. For instance, they translate genetic information U }AIOtUw
into proteins according to the same type of genetic coding. But even where the molecular 'j-U=2,n
processes are the same, the details in the two forms are different and characteristic of the 2x<!>B
respective forms. For example, the amino acid sequences of various enzymes tend to be typically r`\@Fv,
prokaryotic or eukaryotic. The differences between the groups and the similarities within each e^,
IZ{
group made it seem certain to most biologists that the tree of life had only two stems. Moreover, ;+.cD
arguments pointing out the extent of both structural and functional differences between eukaryotes bDm7$
(
and true bacteria convinced many biologists that the precursors of the eukaryotes must have *tv\5KW G
diverged from the common ancestor before the bacteria arose. +prUa
u*
Although much of this picture has been sustained by more recent research, it seems MkhD*\D
/
fundamentally wrong in one respect. Among the bacteria, there are organisms that are Y`#6MhFT7
significantly different both from the cells of eukaryotes and from the true bacteria, and it now wa~zb!y<
appears that there are three stems in the tree of life. New techniques for determining the molecular "vg.{
sequence of the RNA of organisms have produced evolutionary information about the degree to V]GF53D
which organisms are related, the time since they diverged from a common ancestor, and the S^;;\0#NK
reconstruction of ancestral versions of genes. These techniques have strongly suggested that dPbn[*
:
although the true bacteria indeed form a large coherent group, certain other bacteria, the !XM<`H/
archaebacteria, which are also prokaryotes and which resemble true bacteria, represent a distinct g"k4Z
evolutionary branch that far antedates the common ancestor of all true bacteria. {bR2S&=OmK
1. The passage is primarily concerned with RRpY%-8M
(A) detailing the evidence that has led most biologists to replace the trichotomous picture of ;^u,[d
living organisms with a dichotomous one `<g6^ P
(B) outlining the factors that have contributed to the current hypothesis concerning the number of ~( 0bqt3c
basic categories of living organisms '2hy%
(C) evaluating experiments that have resulted in proof that the prokaryotes are more ancient than jvAjnh#
had been expected ;obOr~Jx'5
(D) summarizing the differences in structure and function found among true bacteria, @}:E{J#g
archaebacteria, and eukaryotes K~2sX>l
(E) formulating a hypothesis about the mechanisms of evolution that resulted in the ancestors of *^Ges;5$"
the prokaryotes FRajo~H
2. According to the passage, investigations of eukaryotic and prokaryotic cells at the molecular !icI Rqcf=
level supported the conclusion that v|\#wrCT?

3. According to the passage, which of the following statements about the two-category S9]I[4
hypothesis is likely to be true? @/|g|4
(A) It is promising because it explains the presence of true bacteria-like organisms such as ACi,$Uq6R
organelles in eukaryotic cells. P+CdqOL
(B) It is promising because it explains why eukaryotic cells, unlike prokaryotic cells, tend to @eeI4Jz
form multicellular organisms. od5nRb
(C) It is flawed because it fails to account for the great variety among eukaryotic organisms. 8Iu6r}k?~`
(D) It is flawed because it fails to account for the similarity between prokaryotes and eukaryotes. U# S-x5Gn
(E) It is flawed because it fails to recognize an important distinction among prokaryotes. 7<*0fy5n n
4. It can be inferred from the passage that which of the following have recently been compared i{TPf1OY`M
in order to clarify the fundamental classifications of living things? -j]c(Q MA]
(A) The genetic coding in true bacteria and that in other prokaryotes j6RV{Lkr_
(B) The organelle structures of archaebacteria, true bacteria, and eukaryotes xw_klHL-o

(D) The molecular sequences in eukaryotic RNA, true bacterial RNA, and archaebacterial RNA o$l8"Uv
(E) The amino acid sequences in enzymes of various eukaryotic species and those of enzymes in x {Utf$|
archaebacterial species XHj%U
5. If the “new techniques” mentioned in line 31 were applied in studies of biological cW_wIy\]&
classifications other than bacteria, which of the following is most likely? M>Tg$^lm
(A) Some of those classifications will have to be reevaluated. vs[!B-

Passage3 _[z)%`kay
Stratford-on-Avon, as we all know, has only one industry-William Shakespeare-but there are FWW@t1)
two distinctly separate and increasingly hostile branches. There is the Royal Shakespeare }"WovU{*s
Company (RSC), which presents superb productions of the plays at the Shakespeare Memorial 4[x`\
Theatre on the Avon. And there are the townsfolk who largely live off the tourists who come, not PVF:p7
to see the plays, but to look at Anne Hathaway’s Cottage, Shakespeare’s birthplace and the other ~<<32t'S:
sights. Q njK<}M9
The worthy residents of Stratford doubt that the theatre adds a penny to their revenue. They v{|y,h&]a
frankly dislike the RSC’s actors, them with their long hair and beards and sandals and noisiness. _;5zA"~c#@
It’s all deliciously ironic when you consider that Shakespeare, who earns their living, was himself "IQYy~
/
an actor (with a beard) and did his share of noise - making. 'D`lVUB
The tourist streams are not entirely separate. The sightseers who come by bus- and often B,_K mHItd
take in Warwick Castle and Blenheim Palace on the side– don’t usually see the plays, and some of ^_\m@
them are even surprised to find a theatre in Stratford. However, the playgoers do manage a little ?'a>?al%>
sight - seeing along with their play- going. It is the playgoers, the RSC contends, who bring in "}1cQ|0a
much of the town’s revenue because they spend the night (some of them four or five nights) 7K.],eo0
pouring cash into the hotels and restaurants. The sightseers can take in everything and get out of &F
:.V$
town by nightfall. 6c(b*o
The townsfolk don’t see it this way and local council does not contribute directly to the D:j5/ *
subsidy of the Royal Shakespeare Company. Stratford cries poor traditionally. Nevertheless every $eT[`r
hotel in town seems to be adding a new wing or cocktail lounge. Hilton is building its own hotel (?'vT%
there, which you may be sure will be decorated with Hamlet Hamburger Bars, the Lear Lounge,
Nb3O>&J
the Banquo Banqueting Room, and so forth, and will be very expensive. =s*c(>
Anyway, the townsfolk can’t understand why the Royal Shakespeare Company needs a nM&
